[Radiance-general] Numeric output composited with picture

[Robert Westling]

Hi,

Based on all the previous mail regarding numeric output I have been able 
to generate files containing the location, and illuminance values, 
throughout a daylit space.  Now I would like to be able to take data and 
place the output onto a *.pic of the same area in the grid they were 
taken.  If the readings were taken on 4' centers, I would like to feed 
the data back into Radiance to produce a picture containing those values 
at their actual locations in a grid.

Some ideas:

1.    Pipe the output from lam contining x/y/val into psign and pcompos 
to produce the composited image.  With this idea, the grid dimensions 
would have to be a known pixel spacing.  I'm also not sure if pcompos 
will allow for the translating of the input.
2.     Pipe the output into a new rad file as brightext and use the x/y 
to locate in the scene, the value to act as input into the text field, 
and excluding the mat from the calculation.

Any ideas/suggestions would be greatly appreciated.  Of course if anyone 
has already done this...

One last note, short of rewriting my shell script in perl, is there a 
way to round the rcalc output to two decimal points?

Thanks,

Robert Westling
